WITNESSES Z JAMES P. GOGGIN, OF CENTRAL'FALLS, RHODE'ISLAND, ASSIG NOR T0 GENERAL ELECTRIC COMPANY, A CORPORATION OF NEW YORK.

To all whom it mag concern:

Be it known thatI, JAMES P. GooGIN, a citizen of the 'United'States, residing at Central Falls, county of Providence, State of Rhode Island,have invented certain new and useful Improvements in Blowpipe- Cleaning Devices, of which the following is a specification.

My invention relates to apparatus for 'removing the residue of glass orthe moil which is left on a blow-pipe after the removal of the blown article therefrom. My invention affords a very-efficient and conveniently operable apparatus which may be used in connection with the blowing of glass articlesin any known manner. The advantages of my invention are particularly apparent in connection with. the use of glass blowing machines in whicha removable blow-pipe is employed, as its'use dispenses with the necessity of an operator who would otherwise be required to accomplish its function.

An object of my invention is to produce a device of the character above referred to which will remove the glass residue or moil effectively and rapidly, and, moreover, which is of such construction that the blowpipe may be very conveniently brought into and out of operative relation thereto. Further advantages and features of my invention will appear from the detailed description of a species thereof which follows,

and from the accompanying drawing.

In the drawing, Figure 1 is a side and Fig. 2 is a front elevation of one form of my invention. Fig. 3 is a view in perspective showing the moil removing blades and the position of the blow-pipe with reference thereto. Fig. 4 is an enlarged side elevation of the said blades and their mounting. and Fig. 5 is an enlarged front elevation of the same.

Referring to the drawing, 10 is a shaft journaled in a frame comprising the stand ards 11 and the cross-pieces 12. The said shaft is rotated by any suitable means,

such as the motor 13, by means of the pulley 14 and belt 15. Mounted on the shaft 10 and, preferably, so that they are adjustable thereon, are the blades 16. These are preferably angularly disposed with reference to each other. The said blades are suitably spaced from each other so that the blow pipe may be inserted therebetween. The

adjustmentmay be secured by means of the i 7 screws 17, which pass through the hubs 18,

to which the blades are attached. The said screws engage the shaft 10.

Although the above described apparatus is operable as described, it is preferable to have a means for supporting the blowpipe during the moil removing operation in proper relation to the above described blades. As shown in the drawing, such a support is afforded by the forks 19, the relativeheight of which is such that the blowpipe, when placed in engagement therewith, is given the proper upward inclination so that the end thereof is struck by the ends of the blades. The said forks are supported in the bracket 20, which may be suitably secured to the standards 11.

' It is desirable, also, to provide means for catching the pieces of glass which are detached from the blow-pipe by the blades.

As shown, this consists of a box .21 disposed back of the above described parts, and having an opening 22, and extending somewhat above, below and on each side of the blades and adjacent parts.

During the operation of the above described apparatus the blades 16 are rapidly rotated. The moil carrying blow-pipe is laid upon the guide forks 19 so that the end thereof projects between the rotating blades. The ends of the said blades will then strike the glass and remove the same. During this operation the blow-pipe may be rotated, which will facilitate the operation. The detached glass will be knocked into the box 21 through the opening 22 therein.

It will be apparent that the above described apparatus may be connected up with a blowing machine so that itwill not require a separate motor. It will be apparent also that various changesv may be made in the above described apparatus without departing from the scope of my invention, which is stated in the appended What I claim as new and desire to secure by Letters Patent of the United States, 1s:-

1. In a moil removing apparatus, the combination of a rotatable shaft and radially extending blades mounted thereon in parallel planes, the blades in one set being angularly disposed with reference to the blades of the other set and the two sets bebination of a "rotatable shaft, radially ex-V tending blades adj-ustably mounted thereon ing spaced a suitable distance to receive'the in parallel planes, the blades in one set being angularly' disposed with reference to the blades of the other set and the two sets besmeared ttb su y pa apart as toreeeivetl ie end of ablow-pipe therebetween and operate simultaneously on oppos te sides he e v 3;,Ina'moil removing apparatus, the combination 0L r at e. Shaft a a y extending blades mounted thereon in par allef nla elth e of a be n spaced apart so as. to receive the end of a b1 W-pin hersb v n a dap P- eratesin ultaneously on opposite sides of the blow pipe, and means for supporting a blowpipe' with its end in operative position with reference to the endsof said blades. 7 25 '4, In a moil removing apparatus, the com- 7 of a rotatable shaft and radially extending blades ;mo,unted thereon in parallel planes, the two sets ofblades being suitably spaced apart torec eive the'end of aiblow- Itherebet ee'n. adapted to operate simultaneously on opposite sides of the blow pipe, and a receptacle having an opening therein opposite to, the said'blades and adapted to catch the detached glass.

In a moil removing apparatus the combination of a horizontally disposed rotatable shaft, and two sets of shearing blades mounted on said shaft and extending radially therefrom in parallel planes, said sets of blades being suitably spaced to receive the end of a blow-pipe extending transversely of the said shaft and adapted to operate simultaneously on opposite sides of ablow pipe when the shaft is rotated.

' 6, A moil removing apparatus comprising a rotatable shaft and two sets of adjustable shearing blades mounted on said shaft and extending radially therefrom 1n parallel planes, said sets of plates being suitably spaced to receive the end of the blow pipe and adapted to o aerate simultaneously on opposite sides thereof when the shaft is rot t ed In witness whereof, I have hereunto set myhand this 1'? day of Oct .1914.
